Hammond calls Tube strike 'inappropriate'
Transport Secretary Philip Hammond has said that a walkout by Tube workers is "unnecessary and inappropriate".
Members of the RMT and TSSA unions walked out at 1830BST on Sunday against plans to cut 800 ticket office jobs which they say threaten safety on the network.
Mr Hammond suggested that the rules around balloting for strike action should be "looked at" and urged unions to engage in talks with Transport for London.
